lilly invention relates to cleansing means for receivers for liquid of such character, or in such condition that the walls lof the receivers become fouled and' removal of the accumulations is desired, especially in the case of receivers of glass the walls of which it is desired he kept clean to permit of observation of the contents of the receiver, the particular use for which l have devised my invention heing in connection with receivers into which the lubricating oil from crank cases ofr automobiles is discharged in theoperation of substituting fresh oil for the used oil, and especially in systems in which the used oil is drawn into the receivers loy the enertion of suction therein.

h/fy primary objects are to providea novel, simple and economical uconstruction of cleansing means for receivers in general; to

\ provide for the ready cleansinoof the side walls of the receivers; to provide a structure whereloyl the cleansing operation maybe quickly effected; to provide a structure which will permit of the use ofthe suction. action in theireceiver for effecting the de-l sired idow of the cleansing duid; and other objects as will be manifest from the following description:

Referring in which l have illustrated my invention as incorporated in an apparatus for removing the used' oil from crank cases and of the type disclosed in my pending application for 1U. d. lietters Pat/ent, Serial No. 13,819 tiled March 7, 1925, and involvinga duid-pressure operatedd ejector-device for exerting suction in the receiver to draw the oil into the latter froni the cranlr case, the suction producing' means being in the form ofA a vfluid-pressure operated ejector device Figure 1 is a view in vertical sectional ele# ration of an evacuating apparatus of the type referred to and in which my present improvements are incorporated.

lin. explanation of the illustrated apparatus, as regards those features forming the subject of my said application, it may he statedthat 5 represents a receiver for receiv ing the used oil from the cranlr cases of auto; mobiles, the side wall 6 of this receiver heing constructed of glass to permit of the obf servation of the oil drawn into it. Arllhis receiver is provided in its top with a. duid pressure operated ejector-device l supplied with. compressed air from any suitable source through a pipe il, the suction inlet of the ejector being represented at 9 and ope-nn ing into the upper portion of the receiver 5, it being understood that compressed air discharging vupward from the pipe tl through the ejector-device l and out through the enhaust pipe 10, creates suction, through the opening 9, in the receiver 5.. rlhe pipe il is loosely surrounded hy a pipe 1l which o riens at its upper end into the upper part of the receiver 5 and at its lower end lcormects by `a passage 12 in the bottom of the receiver '5,

with a pipe i3 which leads to a flexible hoseline (not shown) preferably equipped with a fitting, as set forth in said application, to facilitate its connection with the lower drain openings of crank cases to be evacuated of their oil content, and to which the suction created in the receiver 5 is applied through the pipe'll, passage 12 and pipe 13 and the hose-line referred td, totransfer the oil in the crank: case to the receiver 5.. The air pipe is shown as leading outwardly from the standard 111 supporting the receiver .5, this being in accordance with said application wherein the pipe 8 is connected with a valve (not shown) and located exterior of ,the standard llly for controllin the supply of air to the pipe 8, the valve just referred to connecting atts inlet with a pipe' 15 which would lead from the source of com# pressed air for supplying the pipe v8 with the ejector operating pressure. In the continued operation of the apparatus described the .used oil iowing into the receiver 5 causes accumulations to be produced on the glass side wall 6 which prevent visibility of which is desired be exposedto view to observe the condition of the oil, my present improvements being provided forcthe purpose .of effecting the cleaning of such accumulations from the'side The preferred illustrated means provided for this purpose comprise a hollow ring 1G located in the upper part of the receiver 5 vand shown as provided with downwardly opening outlets 1 7 through which the cleansing tluid supplied thereto as hereinafter described, and which may be of any desirable character, as for example gasoline, discharges downwardly against the inner sur# face of the side wall 6to ilow downwardly in a continuous sheet. The ring 16 is shown as connected' to, and supported from, the upper end of a pipe 18 which communicates with the interior of this ring and passes downwardly through thebottom of the rcceiver 5 to which it is rigidly secured as by the fitting represented, at, 19. The receiver 5 is provided with' a receptacle 2() shown as cast integrally with the bottom -portion of the receiver, for storing the cleansing fluid to be supplied to the spray ring 16, the top of this receptacle containing a filler opening equipped with a. removable,

vented, cap 21. The pipe 18 extends 'at its open, lower, end, in communication with the interior of the receptacle 20, valve means,

represented at 22, being provided for convtrolling the entry of the cleansing fluid from the receptacle 20 linto the pipe 18. In the particular arrangement ,shown the receptacle 20 has cast therewith, to extend into its in# terior. a. boss 23 containing an opening 24'- therethrough which communicates with the interior of the receptacle 20, and an opening 25 communicating with the opening 24 and into which thelower end of the pipe 18 extends, the valve 22, shown as a needle valve, screwing in the bottom wall of the receptacle 20 in line. withv the pipe 18 and cooperating with the lower end of the latter to control communication between this pipe and the receptacle 20. i rTo use my cleansing means described, the operator would manipulate the valve rcferred to as controlling the supplying of compressed air to the cause air to flow to the latter and produce suctionV in the receiver 5, the suction thus produced causing the cleansing liquid in the receptacle 20, assuming the valve 22 to be open, to rise throughthe pipe 18 and int,` the spray ring 16 from which latter the fluid discharges against the side wall 6 and -washes away the accumulations above refernedto on this wall. In this connection it may be stated that the receiver 5 would be provided with a valved drain represented at 24 and thro h which the contents of the receiver-V5 woulllgbe discha While I-have illustrated and described a particular construction of device constructed in accordance with my invention, and have shown it as incorporated in a. -particuf lar li 'd' receiver system, I do n ot wish to be nnglrstood as intending to hunt 1t to the 'adapted to flow cleansing fluid ejector device 7, to,

.ing liquid from one receptacle to another and cleansing the transfer receptacle which consists in creating a vacuum in the transfer receptacle to draw the bct'ouling liquid thereto, 'lraining the befouling liquid from the transfer receptacle and drawing into said transfer receptacle by the vacuum produced therein a cleansing fluid to cleanse the same.

2. In apparatus of the character set forth, the combination of a receiver for receiving het'ouling liquid and having a drain, and a single means for effecting, alternately, the transferring of such liquid from a rece tacle to said receiver and the supplying of c cans,- ing Huid to the latter.
